Searching (2018)

This is an interesting way to tell a story, one that is highly linked with the ways and means we communicate in the 21st century.  The back story is told in a series of emails, video files, and instant messaging.  So within about ten minutes you know that a family of three has becomes a family of two because the mom has had a blood cancer, was treated, did well,  then relapsed, didn't do well, and died.  David Kim and his daughter Margo are left alone with each other.  This is beautifully done, in my opinion, and I was sucked into the story in a good way.
The bulk of the story is about Margo disappearing at the end of her junior year of high school and the subsequent search for her.  The search rolls out in the same way that the story started, just with more details, and the occasional live action face to face sequence.  David, not surprisingly, discovers a lot of things about his daughter that he did not know.  He comes to term with the fact that he was affected by his wife's death to the extent that he was less effective as a parent, and he also comes to face the issue of his daughter's ongoing grief.  The rest of the movie is the hunt for what happened.
